Embodiment Construction

[0032] Such as figure 1 As shown, a knowledge map-based construction behavior safety risk analysis and dangerous point identification method provided in this embodiment includes the following steps:

[0033] (1) Establish a knowledge map of construction safety accidents based on relevant construction safety accident reports. First, form a structured table that mainly includes construction safety accidents, behavioral indicators related to behavioral safety, and injury types and locations based on relevant construction safety accident reports, as shown in Table 1. It shows that the construction safety accident knowledge map includes several types of nodes, and nodes are connected by relationships; nodes are key concepts of construction safety accidents, corresponding to the headers in Table 1 (except case numbers), and node relationships are key concepts The connection between them, such as the content of each column in Table 1 is an instance of a node, and the path established...

Abstract

The invention discloses a construction behavior safety risk analysis and dangerous point identification method based on a knowledge graph. The method comprises the following steps: (1) establishing a construction safety accident knowledge graph according to a related construction safety accident report; (2) acquiring accident occurrence data according to the construction safety accident knowledge graph, analyzing field behavior safety data through a modified grey clustering algorithm, and calculating a construction field safety risk level; (3) calculating a behavior index correlation degree through a grey correlation analysis method, and tracking a key behavior index; and (4) identifying dangerous positions related to the key behavior indexes through a knowledge graph path reasoning algorithm. According to the method, objective data of a construction safety accident report are integrated by introducing the knowledge graph, risk feature data are extracted from the knowledge graph, a risk analysis algorithm is improved, dangerous point identification is supported, and the problem that an existing risk analysis and dangerous point identification method is difficult to reflect project and regional features and subjective uncertainty is solved.

Description

technical field [0001] The invention belongs to the field of construction safety risk monitoring, and in particular relates to a construction behavior safety risk analysis and dangerous point identification method based on a knowledge map. Background technique [0002] According to statistics, about 80% to 90% of construction safety accidents in the construction industry are caused by unsafe human behavior. Many studies start from the behavior of workers to carry out construction safety management. Behavior-Based Safety (Behavior-Based Safety) is an effective method to manage workers' behavior to achieve construction safety management. Current research usually develops a behavioral index system based on behavioral safety content to define unsafe behaviors and collect unsafe behavior data. Managers conduct safety risk analysis based on the data, and then associate key behavioral indicators that affect risk changes based on risk analysis results. Finally, Identify risk points...
